Now I go at outdoor activities fairly aggressively, but I consider myself an explorer, not an athelete in training. And while the Forerunner was a lot of fun, it is best suited for those wanting to track their heart rate and performance. It is not a great navigation device. Sure, it can point you in the direction of a waypoint, or navigate along a route, but most GPS receivers have much more flexibility when it comes to navigation. The 301 suffers from a limit of 100 waypoints, and you cannot upload tracks to it. But here’s an amazing statistic…the 301 is the top selling GPS on Amazon! I’m betting there are a lot of runners and lightweight backpackers who consider this the ideal receiver.
